Just to give you some news, I have change my "bad" MD (Salon) with another one and have just re-install the nvidiad board on it.After a new boot and config I retrive the black screen with mouse pointer!I continue my research.

Regards,Philippe

PS: I have no multiple device on the MDs.Only the core have those (4 Zwave controler !)I ask to Hari, what I have to do.

After a Nightmare installation my core is up again.Just UI1 but at least up.

I had issues on installation After Kubuntu8.1 Aptidute and install_from_repo (this was all fine - didn't log into KDM only console)I ran mce-installerNow here the trouble started.Error : package pluto-orbiter not foundpackage was available - don't know why it could not find itAfter hours of trying I found that the setup is messing around with network interfaces(yes I have 2 nics ) whatever I did (changing eth0 and eth1 or just cables) It always stopped there.Disabled network setup in mce-install and run again - a lot of erreors complaining not beeing able to write to logbut at least it installed everything.On start it could not connect to the DCERouter so I had to clean up the devices (many double entries)Had to correct the Database Device for Nic ETH1 as it was in with {Extif} - IMHO some parsing error of the install script

Now setting up MythTV :-)

The Issue with the Blackscreen and Mousepointer is IMO a combination of xorg/driver/UI and some issues in the Launchmanagerto bring up the right screen to the front.

Maybe more when I setup my MD

But for sure dev's have to take a once more a look at it.as there are more and more having similar issues

Now after manual install of Nvidia drivers (proprietary 180) and rerun of AVWizard UI2 without alpha is running (didn't ry Alpha as it is not so important on the CoreBut with standard nv driver MythTV was SlowMotion

All devices up and fine also Orbiter is not complaining about the 127.0.0.1 issue.

Now going to MDThis is an old NB with Radeon Mobility RV250 (9000) GPU

On boot setup runs , Orbiter generated (also checked parallel on WebAdmin) AvWizard faileddriver fglrx is not working with this old GPUhave to use radeonafter selecting RADEON on Webadmin for this MDdriver vesa is usedX is starting upalso AvWizard I could runResult: BLACK SCREEN WITH MOUSE POINTER (and Orbiter Devices not showing up in Spawn file /usr/pluto/lock/

so modprobe drm and radeondepmod -aputting an exit into Xconfigure (see wiki)

xorg.conf stays untouchedX is startingand now Setup Video was started.......

after running through Orbiter Regen is visible and then black screen with mouse pointer

But few seconds later -------- ORBITER is ON :-))))))))) and all devices as well (UI2 without Alpha)

So finally I can say for me it was a non clean installation of the video driver(But maybe some dev made something during the last hours :-) but I think Thom was going to bed)

so now I still have to change the overlay screen and then I'm done

@Philippe

this brings us back to my first idea of xorg :-(so maybe you check and google around to see for more details on your GPU and which driver is bestin any case check also the DISPLAY=:0.0 glxinfo |grep vendorand make a clean uninstall of any previous driver
